That depends on how you want to do it. Me, I upgraded the wiring from the battery positive to the alternator, battery negative to ground, and engine block to ground with 2AWG wire - if you plan on using an amp or any other device which draws a lot of electrical current, you want to do this, because the stock wiring is typically intended only for the stock electrical system, and the thin wire (6AWG - 8AWG) typically used for this has too much resistance to increase the electrical draw without the risk of it catching fire. Once you've done that, how you want to proceed is up to you. If you have an empty slot in your fuse panel, you can use that (although I would recommend you not wire in a linear amp this way, unless you like the idea of frying your ECM). A better way to do it... once I upgraded my wiring, I ran some 4AWG from the battery positive to a fuse panel I bought made by Blue Sea Systems. Then I ran additional electrical and electronic devices off of that. Of course, if you're not drawing too much power, you could simply use a cord which plugs into the cigarette lighter, if you should so wish.
